Portland police are continuing to look for a 13-year-old girl last seen Friday afternoon with a teenage boy at the Lloyd Center shopping mall.

Ayla Marie Venable's mother and two siblings dropped her off at around 1 p.m. at the mall to meet a boy she met over the Internet, according to Sgt. Pete Simpson, spokesman for the Portland Police Bureau.

Ayla was supposed to meet her family two hours later, but she has not been seen or heard from since. Police said she and the boy were last seen at the east end of the mall, outside Sears. Police said their destination was unknown, but that they may have walked toward Holladay Park.

Police and Lloyd Center security searched each store in the mall and scoured surrounding areas, including nearby movie theaters, for the girl and boy.

Investigators said there is a possibility Ayla may have run away, but her family said she has never done that before. The family recently moved to Vancouver from a small town in Kansas, and Ayla is reportedly unfamiliar with the metro area's public transit system. Her family is also concerned because she takes daily medication, police said.

Ayla is 5 feet 2 inches tall, weighing 120 pounds. She has long, straight, light brown hair with her bangs pulled back and blue eyes. She was wearing glasses, a black zippered hoodie with white fleece over a dark-blue shirt. She also wore blue jeans with embroidered pockets and mid-calf gray boots.

Police have identified the boy as Tremane Jarrod Salazar, a 15-year-old reported runaway out of Portland. Police said he is not a suspect, but he is being searched for as a missing juvenile at this time. He appeared clean-cut and clean-shaven with short, dark brown hair, police said. He was described as wearing a gray hoodie jacket, blue jeans and a white knit cap with black trim. He is 5 feet 6 inches tall.

Anyone with information about their location is asked to immediately call 9-1-1. If anyone has additional information, call Det. Mike Weinstein with the Missing Persons Unit at 503-823-0446.
